Axonal growth cone
Joined August 2020
Finally out! 🥳We added a lot of rescue experiments. We now show that Arl13b needs to locate to commissural neurons primary cilium for proper rostral turning of axons. We also further characterized Shh retrograde transport to the soma of comm. neurons.
Delighted to share our latest preprint entitled « A cell-autonomous role for #primarycilia in long-range commissural #axonguidance ». We propose a mechanism involving the neuronal primary cilium during axon guidance at an intermediate target. 🧵(1/7)

Thrilled to collaborate with @ZhixingChen2 Lab @PKU1898!.We tested new PK Mem dyes—gentle, photostable tools to label the plasma membrane in live neurons, making it easier to track growth cone motility & axonal transport. #liveimaging #neuroscience .

This time-lapse captures 17h of axonal growth from a chick dorsal root ganglion explant, seen through the actin cytoskeleton using live imaging. I just submitted this video to the Nikon Small World in Motion competition. Today is the last day to upload yours!😉 #neuroscience

The plasma membrane was stained using the PKmem 555 probe from @Spirochrome. This was my second attempt with it—very promising! Images were acquired with a spinning disk microscope, with one image taken every 5 seconds.

'Ne me quitte pas'. Live imaging of two axonal growth cones meeting, interacting, and then separating. 🔬Can you spot the peculiar event happening between those two?🧐#neuroscience @UZH_Science

Those neurons were cultured in a microfluidic chamber slide to separate axons (right-hand side) from the somata (left-hand side). #FluorescenceFriday
